Rose plant Jacglow

ABSTRACT

A rose variety of the hybrid tea class is provided having high centered, Red Group 49 blooms that heavily produced on long cutting stems, leathery, dark green foliage and resistance to powdery mildew.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of roseplant of the hybrid tea class, which was originated by me by crossingthe variety White Masterpiece, U.S. Plant Pat. No. 2,998, with thevariety Futura, U.S. Plant Pat. No. 3,569.

The primary objective of this breeding was to produce a new rose varietyof the hybrid tea class combining a classical form with high flowerproduction. This objective was substantially achieved, along with otherdesirable improvements, as evidenced by the following unique combinationof characteristics which are outstanding in the new variety and whichdistinguish it from its parents as well as from all other varieties ofwhich I am aware. For example, this new rose variety has:

1. Delicate pink flower color;

2. Long stems;

3. Resistance to powdery mildew;

4. Peduncles that include both glands and prickles;

5. Leathery, dark green foliage;

6. Heavy flower production.

Asexual reproduction of this new variety by budding, as performed atWasco, Calif., shows that the foregoing characteristics and distinctionscome true to form and are established and transmitted through succeedingpropagation.

DESCRIPTION OF THE DRAWING

The accompanying illustration shows typical specimens of the vegetativegrowth and flowers of this new variety in different stages ofdevelopment, depicted in color as nearly true as it is reasonablypossible to make the same in a color illustration of this character.

DETAILED DESCRIPTION OF THE INVENTION

The following is a detailed description of my new rose cultivar, whichhas been denominated "Jacglow". Color terminology is in accordance withThe Royal Horticultural Society Colour Chart except where an ordinarydictionary significance for the color is apparent.

Observations of the buds and flowers were made from specimens grown in agarden at Irvine, Calif. in the Summer.

Flower

The blooming habit is continuous. The bud size is one and one-halfinches when the petals start to unfurl. The bud form is long, pointedovoid. The bud color when sepals first divide is near Red Group 49D;when half blown, the upper side of petals is near Red Group 49D, with agreater color intensity in the center (near Red Group 49C), and thelower side of petals is near Red Group 49D. The sepals have a color nearGreen Group 138B. The surface texture is covered in fine hairs. Thereare three appendaged sepals normally appendaged, and two unappendagedsepals with hairy edge. The receptacle color is near Green Group 138Bwith a funnel shape, medium size and hairy surface. The peduncle ismedium, and has a prickly and glandular surface. Peduncle color ismedium green and the peduncle is stiff, erect and heavy.

Bloom

Bloom size is large, with an average open size of four and one-halfinches, borne singly or several together. The stems are strong and long.The form when first open is high center. The petals then flatten and theouter petals curl back and quill. Under normal conditions there arethirty-five to forty petals. The upper side of petals is near Red Group49C to 49D, and the reverse side of the petals is near Red Group 49C.The base of petals has a small yellow half-moon (near Yellow Group 3B)at the point of attachment to the peduncle with the major color beingnear Red Group 49D. There are no variegations. The general tonality atthe end of the first day shows no change in color. At the end of thethird day, there remains no discoloration.

The fragrance is slight to moderate. The petal texture is thick, of around to deltoid shape, and the form is flat with tips slightly recurvedand outer petals moderately quilled.

The arrangement is imbricated with few, small petaloids in the center.The blooms hang on and dry, and last on the plant for a long period andas a cut flower for a long time.

Reproductive Parts

The anthers are large and many, of yellow color, arranged regularlyaround the styles and are mixed with a few petaloids. The filaments arereddish, the pollen is gold yellow, the styles are reddish, and thestigmas are greenish white.

Plant

A vigorous, upright growth of bush form.

Foliage

Medium size, normal in quantity. The new foliage is bronze colored thatturns dark green as old foliage. Normal mid-stem leaves have fiveleaflets.

The leaflets are of an oval pointed shape, are leathery, and have aserrated edge. The serration is single and small in size. Petiole rachisis reddish, and petiole underside is rough with prickles. Stipules arelong and the edges are glandular. The foliage is resistant to mildewunder normal growing conditions at Irvine, Calif.

Wood

New wood is reddish, with a smooth bark. Old wood is green with a smoothbark.

Prickles

There are an ordinary number of prickles on main canes from the base andon laterals from the main canes. The form is medium and hooked downward.Color when young is red.

Parentage

The seed parent was the variety White Masterpiece, U.S. Plant Pat. No.2,998. The pollen parent was the variety Futura, U.S. Plant Pat. No.3,569.

Classification

Botanical is rosa hybrid. Commercial is hybrid tea.

I claim:
 1. A new and distinct variety of rose plant and parts thereofof the hybrid tea class substantially as herein shown and described,characterized particularly as to novelty by light pink, high centeredblooms, heavy flower production on long stems, leathery, dark greenfoliage, resistance to powdery mildew, and peduncles including glandsand prickles.
